"""Fixed puck-carrier/receiver scenario, natural defending AI and skating after setup.
Setup spans nine frontend frames to settle the captured CPU registers and pads;
no positions/velocities are reset during the 140 measured frames.
The two attackers are idle human-controlled actors: no repeated position resets.
